GROUND STATE PROPERTIES OF Ds ISOTOPES WITHIN THE RELATIVISTIC MEAN FIELD THEORY

摘要

The ground state properties of Ds (Z = 110) isotopes (N = 151 -195) arestudied in the framework of the relativistic mean feld (RMF) theory within theparameters NL-Z2.The pairing correlation is treated within the conventionalBCS approximation.The ground properties,especially isotopic shift,competi-tion between α-decay and spontaneous-fission (sf) and single particle spectraare analyzed for Ds isotopes to fnd new characteristics of superheavy nuclei(SHN).The isotopic shift appears evidently at neutron number N = 184,whichis the most impressed result.
